@minnied I have had 8 Evenity treatments and for me the first three had side effects of very sore arms. My body must be adjusting to the injections since as I have no more soreness or pain in my arms. The nurse who does the injections always rubs my arm afterwards to help disperse the medication away from the injection site. Another nurse told me some patients prefer to have the injections in their belly. Best wishes for you to have good results and less side effects going forward.
